| Abstract: | When high-speed train enters into a tunnel,a series of aerodynamics effects such as pressure variation in carriage noises were created.Model test is an efficient method to research pressure variation.In this paper,using high-speed train aerodynamics model research system,the propagation mechanism of compression wave,which created when high-speed train entering into a tunnel was resear ched,at the same time the effect of velocity of the model train and the ratio of train with tunnel was analyzed,the result is helpful for future research. |
